9 Claims.

This invention relates to a device for dispensing articles such as pins, paper clips, etc., mounted on a strip.

An object of this invention is to provide a device for dispensing pins, clips, etc., mounted on paper strips, whereby the articles are presented in position for easy and quick removal.

Additional objects of the invention will become apparent from the following description, appended claims and accompanying drawing wherein:

Figure 1 is a perspective view of one embodiment of the device constituting the instant invention.

Figure 2 is a section taken on line 2-2 of Figure 1.

Figure 3 is a section taken on line 3--3 of Figure 1.

Figure 4 illustrates in perspective a detail of the device.

The instant invention contemplates a device for dispensing articles such as pins, clips, etc., mounted on a strip and which is usually spirally wound to form a. roll or coil. According to the instant invention, thestrip carrying the articles to be dispensed is fed. in a suitable position through a guide mechanism. which is so devised and constructed as to present one'or more of the articles to be dispensed in position for easy and quick removal by the fingers. The guide mechanism is provided with an adjustable element, whereby the guide can be adjusted for use with articles of different heights. Since pins, for example, are generally mounted on strips which are spirally wound on themselves, the device also includes means for rotatably supporting a coil of the spirally wound pin strip.

Referring now to the drawing wherein an embodimentof the invention for dispensing pins is disclosed and wherein like reference numerals designate like parts, the, reference numeral I designates a pin strip carrying pins 2 mounted transversely thereon at predetermined spaced in tervals. The pin strip 1 is wound on to a hollow core 3 to which a disc 4 is attached by suitable fastening elements 5, whereby a coil or roll 6 is obtained. The disc 4 is generally circular in shape and of a diameter. slightly greater than the overall diameter of the coiled pin strip. 7

It is to be noted that in the roll 6 the pins extendin. a direction parallel to the vertical axis of thecore with the pin heads being freely exposed; Though in the embodiment disclosed the upper surface of theroll 6 is free, if desired a cover plate (not shown) may be applied thereto in any convenient manner.

The present invention comprises a device for dispensing pins carried on a pin strip and formed into a roll of the general type previously explained. In accordance with the principles of the invention, the device is provided with means on which the roll 6 together with its appurtenant elements may be rotatably mounted. In the embodiment shown in the drawing this means consists of a stud l rigidly secured, by any convenient fastening means 8, to the base 8' of the device. The diameter of the stud 1 is slightly less than the diameter of the bore in the core 3, in order to provide some clearance therebetween. As a consequence, the core 3 can be expeditiously and quickly mounted thereon and, due to the clearance, the roll 6 and its appurtenant elements are rotatableabout the stud I. If desired, the stud I may be rotatably mounted on the base and the core 3 non-rotatably mounted thereon.

It is to be understood that the disc 4 need not be a part of the original pin strip coil package. In such a case the core 3 is secured to the disc 4 either prior to or during placing of the pin strip coil in the device.

As previously mentioned, one of the essential features of the instant invention resides in presenting'the pin strip I together with the pins 2 in such a position that one or more of the pins 0 2 may be quickly removed by the fingers of the individual desiring to use the pins. This is secured by feeding the pin strip I together with the pins in a vertical direction between a pair of spaced substantially parallel members 9 and I0 secured to the base 8 in any desirable manner as by tongues 9' and 10'. The members 9 and ID are preferably provided with oppositely disposed depressions H intermediate the ends of the respective member. Though in the preferred form bothmernbers 9 and I!) are provided with depressions, it; is to be understood that only one of said members may be provided with the depression. The depressions are of such width and depth as to present one or more pins in position for removal.

Due to the fact that the pin strip and pins are preferably fed in a vertical position, the individual desiring to remove the pins does so by gripping the heads of the pins extending in the depression with the fingers. When one or more of the pins 2' are removed from the strip l by the fingers, as. shown inFigure 1, there is exerted a pulling effect. with the consequence that the pin strip together with the pins not. exposed in the depression I! are forced upwardly; In order to prevent the removal of the pin strip from between the legs 9 and Hi, there is provided means which prevent the upward movement of the pin strip when the pins are removed. These means may take various forms. Generally, they may be strips or bridges, rounded or flat as desired, extending over and connecting the upper edges of the members 9 and it. Since the pulling effect is strongest at the place where the pins are removed, the retaining means are positioned adjacent the depression as shown by the reference numerals l2 and iii.

The space between the members 9 and I is of sufficient width so as to accommodate pin strips of various thicknesses. The height of the members 9 and i0, and particularly the height of these elements at the places where they are bridged by the elements i2 and I3, is such as to accommodate the longest pins made. The members 9 and i9 may be of any desired length.

In order to present smooth surfaces so that the strip I and the pins 2 may be guided between the members 9 and i0 Without damage and with great facility, the rear end of the member I9 is curved and flared as shown by the reference numeral M. The curved portion I4 is of such curvature that it will readily accommodate and conveniently guide the pin strip together with the pins in the desired manner between the members 9 and I0, irrespective of whether the roll 6 is of full diameter or of a reduced diameter occasioned by the unwinding during the use thereof.

In the preferred form of the invention the device comprising the elements 9, l9, ll, l2, i 3 and M are made of one piece. As shown in Figure 1, the device just referred to comprises an inverted U-shaped member having a cut-out portion (depression) in the upper edge thereof, and the bridges l2 and 53 formed by the horizontal leg of the inverted U-shaped member.

Pins are made of various lengths and, in order to make the dispensing device operative with any size of pin, there is provided adjustable means whereby the effective height of the passage between the members 9 and I9 may be adjusted for use with pins of any height. Various means may be used for this purpose.

In the form illustrated in Figure 4, this element comprises a U-shaped member having vertical legs i5 and i5 and a horizontal leg or bottom i6, which may be rounded or fiat as desired. The bottom i6 is of sufficient width so that the legs I5 and I5 frictionally and slidably engage the inner surfaces of the members 9 and H].

In the preferred form of the invention, the ends of the leg it: are bent rearwardly over to form inwardly extending flanges I1 and I8. Each of these flanges frictionally slidably engages the marginal portion of the respective edge of the element 9. Each of the flanges is further provided with tabs I9 and 29 whereby by gripping the same the U-shaped element may be raised and lowered to increase or decrease the effective height of the passages between the members 9 and [0 to the desired size. The forward end of the horizontal leg I6 is also curved in order to permit easy ingress of the pin strip. In the form shown in Figure 4 this end portion is curved and bent upon itself as shown in Figure 4 and designated by the reference numeral 2|.

Though in the form illustrated the adjusting mechanism is maintained in its desired position by friction, it is obvious that such a construction is not necessary. Other means for slidably mounting the adjusting element may be utilized.

For example, a set screw may be provided in each of the flanges H and I8 which may be used in the adjustment of the device. Similarly, the flanges I! and i8 as well as the finger tabs [9 and 29 may be wholly omitted. In such an embodiment the leg l4 may be provided with a screw which cooperates with a slot in opposed relationship in the leg 9. Thus, the adjustable element may be raised or lowered as desired, with the consequence that the effective height of the passage between the legs 9 and i9 may be increased or decreased. In such a construction nuts, preferably wing nuts, cooperating with the screws may be used to secure the members in the desired position.

In operation, a roll of pins is mounted on the stud I and the end thereof is fed through the passage between the legs 9 and Ill. The adjustable element disposed between the legs 9 and i9 is then raised or lowered as may be necessary, in order to make the effective height of the passage between the elements 9 and it such as is necessary to accommodate the size of the pins being dispensed. After such adjustment, the elements assume the position shown in Figure 3. The individual then removes the pin as may be desired. When the pins exposed in the depression have all been removed, the operator then pulls the strip extending beyond the device vertically, whereby other pins are positioned for removal.

Since it is obvious that various changes and modifications may be made in the above description without departing from the nature or spirit thereof, this invention is not restricted thereto except as set forth in the appended claims.
